2 Claims.

Thisinvention relates to cooking and heating stoves or ranges and isdirected more particularly to an improved kitchen range constructionhaving a circulating heater contained therein in such a way as to berelatively inconspicuous yet readily available for efficient andeconomical use.

It is one of the principal objects ofthis invention to provide a novelcooking range having a heating compartment or device incorporatedtherein which is adapted to send warm air into the room in which therange is contained. As will appear, a special feature of the inventionis that the range has an outward appearance which is substantiallysimilar to that of, or at least not objectionably different from, rangesnow in common use so as to be commercially saleable while at the sametime it has new and distinct advantages over conventional rangeconstructions.

According to this invention, the range has a novel air-duct box orcontainer therein which includes a circulating heater device soconstructed and arranged as to send warm air into the kitchen or otherroom of the house. appear, the device is contained within a particularcompartment of the range which would probably otherwise not be utilizedto as good a purpose and the arrangement is such that the desired roomheating is achieved without inter- I fering with the other functions ofthe stove.

The range may have the usual cooking gasburners with a baking oven andbroiler therebelow, and by reason of the unique arrangement about to bedescribed, there may also be a so- 1 called utility drawer orcompartment at one side of the top of the range. The construction issuch that said utility drawer and thetop gasburner compartment may besubstantially coplanar both for the sake of appearance and convenienceand the air-duct box above mentioned is preferably disposed below theutility compartment and so associated with the other parts as to providea so-called warming closet between itand the baking oven or broilercompartment.

A still further object of the invention is to provide a unitary andcompact range construction wherein there is a room or air heating devicewhich is normally more or less concealed from view and which utilizesspace in the range which would otherwise not be used. That is to say, Inot only provide for the disposition of room-heating means in a part ofthe range which in the ordinary case is wasted space but my constructionis such that the usual unsightly ap- As Will the description proceeds,the invention consists in certain novel features of construction and inthe combination and arrangement of parts as will be hereinafter moreparticularly pointed out in the claims hereunto annexed and more fullydescribed and referred to in connection with the accompanying drawingwherein;

Fig. 1 is a front elevational view of a construc-- tion embodying thefeatures of the invention with parts in section to explain certainfeatures thereof;

Fig. 2 is a partial end elevational view of the apparatus of theinvention;

Fig. 3 is an end elevational view of what is shown in Fig. 1 with partsin section, also for the sake of clearness;

Fig. 4 is a rear elevational view of the upper part of the apparatusshown in Fig. 1 with dotdash lines to explain certain features thereof;and

Fig. 5 is a sectional view on the line 5-5 of Fig. 4.

Referring now to the drawing more in detail, the invention Will-be fullydescribed.

In general the range will include front and rear walls 2 and 4respectively and end walls such as 6 shown in Fig. 2. A so-calledsecondary air chamber I0 is located beneath one end of the cooking top,and this contains what are called top-range gas burners having gas-cocksI 2.

Below the compartment l0 there may be oven and broiler compartmentsnormally closed by doors l4 and I6 respectively. There may or may not bea back-splash wall member I8 extending vertically and upwardly from therear of the range.

At a side of the range burner compartment there may be a utilitycompartment 20 for containing various kitchen implements, for example,and it may have a drawer therein. as shown. It

is preferably substantially coplanar with the.

chamber in so that a relatively flat cooking top is provided.

There is a wall 30 extending transversely of the range between the frontside thereof and the rear wall, located at one side of the oven andbroiler compartments. This serves to provide a chamber which preferablyhas a transverselyextending shelf member 32 separating it into an upperwarming closet 34 and a lower compartment 36 which may or may notcontain a burner device of any desiredconstruction for transferring heatto the shelf and thence to the compartment thereabove so that dishes orthe like may be kept warm.

A casing 50 is contained within the storage compartment formed betweenthe wall 30 and the adjacent end, front and rear walls of the range andthis has its walls spaced from the in- 20, 1939. Such a unit isrelatively self-contained and compact, as will be obvious, and istherefore particularly suitable for insertion in such a compartment ashas been described and for co-operbodiments are therefore to beconsidered in all respects merely as being illustrative and not as beingrestrictive, the scope of the invention being indicated by the appendedclaims rather than by the foregoing description, and all modificationsand variations as fall within the meaning and purview and range ofequivalency of the appended claims are therefore intended to be embracedtherein.

What it is desired to claim and secure by Letters Patent of the UnitedStates is:

1. The combination of the vertical side partition, and lower and upperwalls forming oven and adjacent compartments of a range with roomheating means independent of said oven comprising, an inner 1 casingwholly within the said adjacent compartment having an open lower sideand vertical side and upper walls parallel with and spaced from adjacentwalls thereof forming therewith an buter insulating air space around theinner compartment, a hollow heater unit, within the inner casing havingan open lower side and vertical side and upper walls spaced fromadjacent walls of said inner casing ating with the usual construction ofa range can thus be maintained so that any advantages thereof areretained. To put it another Way, it

is such that the maximum efiiciency of the cooking and baking or heatingcompartments is still maintained while at the same time the room may beheated.

The air heater has a flue 10'- and, of course, the cooking and/orbroiling part must also have a flue such as is indicated by I5.According to the preferred form of construction, these flues areconnected by a flue member 12 which leads into a chamber or casing 14 onthe back of the range and the whole combination is 'so arranged andconstructed as to lead the products of combustion from the lower burnerto a point above the level of, or at least on a plane with the point ofdischarge of the products of combustion from the This may beaccomplished in various ways but is best achieved, according to thisinvention,'by providing a flue chamber 12 which extends upwardly on anangle between, and connecting from being directed other than upwardly oroutwardly away from the stove or range.

The walls of the shell or casing are preferably spaced from the walls ofthe compartment within which it is'contained and its lower end is open,as shown. This provides an air-duct box and the lower wall of thestorage compartment is preferably perforated, as shown, to permit theintroduction of'air into the air-circulating heater chamber for obviousreasons.

The latter chamber has an outlet connection which is preferably coveredby a grill-like member 60. This may obviously vary in construction andits prime purpose is to permit air which is warmed by unit D to beexpelled into the room.

The invention may be embodied in other specific forms without departingfrom the essential characteristics thereof. Hence, the present emandproviding therewith an inner warm air circulating space around the saidheater, a burner at from the heater unit extending through said innerand outer air spaces and certain vertical walls to said stack, and thesaid lower wall of the outer casing provided with an opening to permitair to enter said heater unit, the insulating space around the innercasing and circulating air space around the heater.

2. The combination of the vertical side, partition, and lower and upperwalls forming an oven and adjacent compartments of a range with roomheating means independent of said oven comprising, an inner casingwholly within the said adjacent compartment having an open lower sideand vertical sideand upper walls parallel with and, spaced from adjacentwalls thereof forming therewith an outer insulating air space around theinner compartment, a hollow heater unit within the inner casing havingan open lower side and vertical side and upper walls spaced fromadjacentwalls of said inner casing and providing therewith an inner warm aircirculating space around the said heater, a burner at the open lowerside of the heater unit. a hollow connection between adjacent verticalwalls of said inner casing and adjacent compartment adjacent the upperends thereof extending horizontally through the circulating air spaceproviding a passageway from the circulating space outwardly of the rangeinto the room below the upper side thereof, a stack, the said lower wallof the outer casing provided with an opening to permit air to enter saidheater unit, the insulating space around the inner casing andcirculating airspace around the heater, and flue
